Create a tree, which has h (h0) layers, and its each node has w (w0) sub-nodes.Please complete the following incomplete solution.
#include stdlib.h
#include string.h
struct tree{
char info;
p_sub; //link to sub-nodes};
// allocate memory and initiate
void dnode ( struct tree* tmp )
{
= malloc( sizeof (struct tree) );
= 0x41;
= NULL;
}
struct tree *dtree (struct tree* subtree, int height, int width)
{
int i;
if (!subtree ) //if necessary, allocte memory for subtree
denode(subtree);
if ( height == 1 )
return subtree;
else if ( height == 2 ) {
struct tree *leaf = NULL;
for ( i=0; iwidth; i ) {
denode ( );
;
leaf = NULL;}
return subtree;}
else {
for ( i=0; iwidth; i ) {
}
return subtree;
}
}
main()
{
.........
struct tree *root = NULL;
root = dtree (root, h, w); // h and w are integers get from input
.........
}
